In a strong hydrogen bond, the low-barrier hydrogen bond (LBHB) with a low transfer-barrier energy for the proton is often observed in a biological molecule as one of hydrogen-bonds with the same pH values between hydrogen bonding donors and acceptors.
The transition metal complexes connected with LBHB would be easily stabilized mixed-valence states by a H-bonding proton transfer,
switched by the electrochemical redox reaction.
While, each localized state of the PCET (proton-coupled electron transfer) reaction observed through an isolated molecule are affected by solvation in solution. However, in crystal without solvation, the mixed-valance metal complexes connected with LBHB are often observed a PAET (proton-assisted electron transfer) reaction simultaneously transferred both protons and electrons, which has been clarified on a physical property continuously fluctuated a proton and electron. Therefore, we would like to study on evolution of a functional material and elucidation of the mechanism of a PAET crystal. (1) Elucidation of PAET Mechanism by Dimer Complex Crystal with LBHB (2) Study on Molecular Conductor of Honeycomb Sheet Crystal Connected with LBHB (3) Development of PAET Conductor Controlled the Multi-dimensionality. As a result, we would like to elucidate a new molecular material coupled with a proton transfer and electron transfer without solvation.
